New Generation SICK W12 Photoelectric Sensors Released: 37-Year Classic Gets Full Technical Upgrade

Introduction

In the industrial photoelectric detection industry, SICK W12 series is a time-tested classic. First launched in 1989, this photoelectric switch has served global markets for 37 years. Over 30,000 customers worldwide have purchased millions of units, which stably handle complicated and challenging detection tasks in harsh working conditions.

Based on nearly four decades of market experience and technical iteration, German SICK has officially launched the new-generation W12 photoelectric sensor. It brings comprehensive upgrades in durability, detection accuracy, easy operation and digital interconnection, delivering far better value than expected for all industrial sites.

Core Advantages for End Users

1. Ultra Rugged Structure for Tough Industrial Environments

It features excellent chemical resistance, thermal stability and mechanical strength, equipped with a durable metal housing. The sensor can resist dust, oil, moisture and impact, perfectly matching automotive, logistics, packaging and metallurgy industries to lower equipment replacement and maintenance costs.

2. Outstanding Detection Performance Against Strong Light & High Speed

Supported by SICK self-developed Optical Experts optical algorithm, it works stably even under strong ambient light. With a maximum switching frequency of 1.5kHz, it can accurately capture targets on high-speed assembly lines and avoid missing detection or false triggering.

3. Complete Model Portfolio for All Kinds of Automation Demands

A full range of standard and professional variants are available, including multi-mode WTM12 and WLG12 sensors. Multiple sensing modes (through-beam, retro-reflective, diffuse) are optional. Users can pick suitable configurations according to material type, detection distance and installation space.

4. User-Friendly Operation & Intelligent IO-Link Digital Connection

• BluePilot integrated rotary knob supports visual, precise and quick calibration, friendly for new operators;

• IO-Link communication is built-in to transmit real-time data: temperature, detection distance, receiver signal level, switching output and sensing quality;

• Digital twin technology supports remote equipment diagnosis, status monitoring and parameter setting, greatly accelerating smart factory upgrading.

Three Groundbreaking Optical Technologies

The biggest highlights of the new W12 are three innovative optical designs that solve long-standing industry pain points of traditional photoelectric sensors:

1. PinPoint Pro LED High Precision Light Spot

Compared with the old PinPoint LED, its light energy density is doubled with a compressed rectangular light spot:

• Wider effective sensing range

• Better tolerance for black & white object offset

• Less influence from installation angle

• Stronger resistance to ambient stray light

2. Hybrid Infrared LED Light Source

Pure infrared sensors lack visible alignment spots while traditional red LED sensors have limited detection distance. SICK hybrid LED solves both problems:

• Main infrared beam provides longer sensing distance and stronger anti-interference for dark, light-absorbing objects;

• Temporary visible red alignment light can be activated for 30 seconds via button or IO-Link command for easy on-site calibration;

• Infrared and visible light share the same optical path without position deviation.

3. Twin-Eye Dual Receiving Technology

Ordinary single-channel sensors often misfire when detecting glossy metal, transparent plastic or uneven workpieces. WTS12 adopts dual receiving channels and self-developed ASIC chip:Dual-channel signal comparison effectively prevents false detection caused by reflective, perforated or irregular workpieces. Matched with LineSpot linear light spot, it realizes ultra-stable detection for thin and highly reflective materials.

37-Year Classic Reborn for Full-Scene Smart Manufacturing

From setting industry standards in 1989 to integrating PinPoint Pro LED, hybrid infrared light source and Twin-Eye technology, the new W12 is no longer a simple detection switch. It becomes an all-in-one intelligent sensing unit with tough housing, high-precision optics and digital communication.

It is widely applicable to logistics sorting, packaging & printing, auto parts processing, lithium battery new energy, machine tools and automated warehouses. Whether you need to replace old sensors on existing production lines or build new intelligent factories, it can cut operating costs, improve detection accuracy and simplify digital access.

Conclusion

After 37 years of market verification, the iconic W12 series has completed comprehensive technical renewal. The new generation SICK W12 photoelectric sensors are now fully released.
